SAFE OR VAULT DOOR BOLTING MECHANISM.

' SPECIFICATION forming part of Letters Patent N 0. 679,379, dated July 30, 1 901. Application filed November 2, 1900. Serial Not 35,198. (No model.)

To all whom it may concern.-

Be it known that I, HENRY D. HIBBARD, a citizen of the United States, residingin Plainfield, in the county of Union, and State of New Jersey, have invented certain new and useful Improvements in Safe or Vault Door Bolting Mechanism, of which the following is a specification.

This invention relates to bolting mechanism for safe or vault doors, one object of the invention being to provide improved bolt mechanism therefor.

A further object of the invention is to provide an improved organization of bolt 1nechanism in which an increased number-as, for instance, double the ordinary number-of bolts may be used around the periphery of the door without proportionately increasing the area over which the inner ends of the bolts are distributed, the present invention being an improvement over that shown and described in my contemporaneously-pending application, Serial No. 16,402, filed May 12, 1900, now Patent No. 662,435, dated November 27, 1900.

In the drawings accompanying and forming part of this specification, Figure 1 is a rear View of a door with this improved bolting mechanism shown in dotted lines. Fig. 2 is a sectional view taken in line a a, Fig. 1. Fig. 3 is a view of the inner side of the back plate with the boltactuating mechanism located thereon, all the bolts being removed with the exception of the inner ends of a pair thereof. Fig. 4 illustrates the action of thebolts when shifted into and out of their locking positions. Fig. 5 is an edge view of the parts shown in Fig. 4, and Fig. 6 is a perspective view of one of the bolt-heads.

Similar characters of reference indicate corresponding parts in the different figures of the drawings.

In the present instance the door 2, which may be of any desired shape, but shown herein as circular, comprises a body 3, having a rear wardly or inwardly extending peripheral flange 4, provided with the desired number of bolt apertures or openings 5 for the passage of the bolt-heads. Secured to this flange is a back plate 6, which is adapted to support the locking mechanism, said plate being pro- Each of the bolts 14. may comprise a head or bolt proper, 15, and a shank 16, pivotally connected or hinged together, or the bolt may consist of one piece, the inner end of such shank being located on a pin of the rocking plate. The inner ends of each pair of bolts of the series overlap and are located on. the same pin or pivot, whereby an increased number of bolts may be located around the periphery of the door without unduly increasing the area over which the inner ends of such bolts are located. In my prior construction referred to the bolt-openings 5 in the flange were shown as tapered to permit the lateral movement of the bolts during the shifting thereof, and this will be the formation when each of the bolts is made as one member. In the present instance, however, the bolt-openings are shown with their side faces straight, whereby the bolt-heads move in a straight path, the hinge connection between such heads and their shanks permitting lateral movement of such shanks on the rocking of the plate 10. For rocking this plate, thereby to shift the bolts into and out of theirlocking position, a worm-shaft 12 is mounted in suitable bearings 13 on the back plate. For rotating this Worm-shaft suitable actuating mechanism is provided controlled by suitable combination-locks, such mechanism preferably being in duplicate. Splined adjacent to each end of the worm-shaft 12 is a clutch member 14, with which one end of a counterbalanced pivoted lever 15 is in engagement, such lever being in operative connection with a combination -lock 16, by means of which it is shifted. A loosely-mounted clutch member 17 is located on said shaft adjacent to each splined clutch member. Each of these looselymounted clutch members carries a worm-gear 18, in mesh with acorresponding gear 19, located on a spindle 20, projecting at the outer face of the door and mounted in bearings 21 and 22, located one at each side of said gear 19, one of said bearings being carried by the back plate.

By providing duplicate combination-locks and actuating mechanisms the bolts maybe operated by one lock should the other for any reason become inoperative, whereby the necessity of opening the safe by force is avoided.

In use when either one of the combinationlocks is properly operated the proper clutchshifter 15 will be moved to shift a splined clutch member 14 into engagement with a looselymounted clutch member 17, whereupon on the rotation of a spindle 20 by the crank usually provided for that purpose the Worm-shaft 12 will be rotated to rock the rocking plate and thereby shift the bolts into or out of engagement with the jamb of the doorway, the bolt-heads moving in a straight path, while the shanks thereof are moved laterally, wherebyatoggle action of the bolts is secured. When the door is made of unmachineable metal, by which is meant metal that cannot be practically worked by cutting or boring tools-such, for instance, as manganese steelraised surfaces 23 are provided for the bolts to work upon, whereby the necessity of grinding a large area of metal is avoided, this feature being more particularly described in my prior application above referred to.

When a large number of bolts is desired, especiallyin large doors, it is necessary that the lateral movement of such bolts shall not interfere with the proper location of the spindles and other parts, and by locating the inner ends of each pair or set of bolts on the same pivot room is thus provided for the proper location of such necessary elements.
